IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 114,272, datelSeptember 13, 1864.

To all whom, it may concern:

Be it known that I, WILLIAM S. KELLY, of Schenectady, coun ty ot'Schenectady, and State ot' New York, have invented a new and ImprovedPump; and I do hereby declare that the following is a full, clear, andexact description thereof, reference being had to the accompanyingdrawings, makin ga part of this specification, in which- Figure lis adiametrical section through my improved pump. Fig. 2 is a sideelevationot' the pump. Fig. 3 is a view of the piston-rod and valve-boxremoved from the pump-cylinder. Fig. et is a horizontal section throughthe stntlng-box, taken at the point indicated by red line xx, Fig. 1.Fig. 5 is a section through the discharge-orifices of the pistonrod,indicated by the red line y y, Fig. 3.

Similar letters of reference indicate corresponding parts in the severalfigures.

rIhis invention relates to certain new and useful improvements in pumps,wherein I use a center-discharge or hollow piston-rod, and conduct thewater from the base ot' the pump up through said piston-rod into astationary vessel, from which latter the water is finally dischargedthrough a pipe and air-chamber.

My invention also relates to certain improvements on thev pumps whichhave already been patented to me, in so far as the employment of ahollow piston with upper and lower passages for the water and one valveclosing both passages, and also the use of a stationary receiving-vesselfor receiving the water from the piston rod and discharging it into theservice-pipe.

The object of my invention is to combine the receiving-vessel with thebody of the pump in such manner that the latter is rendered more simpleand compact and the necessity of employing a separate receivingvesselrendered unnecessary, all as will be hereinafter described.

To enable others skilled in the art to make and use my invention, I willdescribe its construction and operation.

In the accompanyingdrawings, A represents a valve-box, which is suitablybolted to the base of the pumpcylinder B and side passage, B. rIhisvalve-box is divided into two compartments by a vertical division, a,which compartments are adapted for receiving ballvalves b b", that restupon seats a. c2 and prevent water from escaping downward after it onceenters the pump. As the spaces within which the ball-valves b b arearranged are as large as the chambers B B above them, nar row bars aresecured over these balls, as shown at c c', which prevent the latterfrom rising too high when the water is drawn into the pump.

The pumpcylinder B is provided with a side passage, B', whichcommunicates with it through a port, d, for the purpose of causing thepiston U to draw water into the cylinder B in its descending stroke, asindicated by the course ot' the arrowsin Fig. 1. When the pistou C isdrawn upward, the valve b', at the base of passage B', falls and closesthis passage at the same time that the valve b opens and allows water torush into the cylinder B beneath the piston C. The piston G isconstructed with a valve-chamber, c, and an upper and lowerinduction-orifice, e e2, and within the piston-chamber e a ballvalve, f,is applied, which closes the upperorice, c', as the piston descends, andthus allows water to enter through orifice c2, or as the piston asccndsthe ball j closes thelower oricc, e2, and causes the water to enterthrough oritice e. The Water which enters the piston-chamber c is allforced upward through a hollow piston rod, C', and discharged into areceiving-vessel, G, through openings g g, from whence it is conductedottl through a discharge-pipe that is applied to the oriiice g'.

All that portion ot" my pump which relates to the mode of getting waterinto the cylinder B and forcing it out ot' this cylinder may beconstructed upon the princi ples which are clearly set forth in mypresent patents, dated February 25, 1862, and August 23, 1864, fordouble-acting hollowpiston force-pumps; but I do not contine my presentinvention and improvements exclusively to such pumps, as other forms maybe conveniently employed for forcing the water through a hollow pistoninto the receivingchamber G.

The receiving-vessel G is represented in thc annexed drawings as beingcast with t-he body of the pumpi. e., the cylinder B and side passage,B. Heretofore this vessel has been a separate contrivance and isolatedfrom the body of the pump; but as objections attend such an arrangement,I now cast or otherwise apply this vessel directly to the top of thepump-cylinder. In order to accomplish this it is necessary to provide ameans for packing the piston at the point wherelthe two chambers B and Gare joined. This is done by casting or otherwise forming on the insideof the vessel G, at its lower end, an annular recess, h., which ispacked with any suitablematerial which will i'orm a water-tight jointaround the piston-rod C and at the same time allow this piston to movefreely through it. It' the parts B and G are cast in one piece, thispacking is introduced through holes z' t', which are afterward closed bymeans of plugs j j; but if the parts B and G are cast separately andthen bolted together, a packingbox may be introduced between them, orthe annular recess h may still be used. The advantage of the openings it' would be felt in either case, as they admit of a renewal ot' thepacking at pleasure.

As the packing at the junction of the two chambers B and G will preventany of the water in the chambers B B from escaping around the pistonrod, all the water must necessarily pass up through the piston-rod, as Ihave above described, and enter the receiving-vessel G through theopenings g in this piston-rod. Ihat portion of the piston-rod G whichextends above the openings g is tubular merely for the purpose ot'giving lightness to it; but, it' desirable, this extension of the rodmay be made solid, with a suitable coupling on its upper end forconnecting the pump-rod H to it. It' made tubular, the upper end shouldbe closed, so as to prevent the escape oi'water at this point. Thatportion of thel rod C which extends above the dischargeopenings g passesthrough the upper end of the vessel G, and through a suitablestuffingbox applied at this point, so that the openings g can dischargeall the water directlyinto the vessel G, and also so that the pump-rodcan be applied to the piston above the. vessel G, and a stroke given tothe piston-rod equal t0 the length of said vessel. The discharge-pipe,which is not shown in the drawings, is applied to the orifice y at theupper end of vessel G, as shown in Fig. l, to which orifice the water isconducted by means of and offset, Gf; but, if desirable, the chamber G-may be made of sufficient diameter to admit ofthe application of thedischarge-pipe directly to the side or end of the said vessel. The ott'-set G serves as an elbow for the dischargepipe, which latter risesvertically through the well, and it also serves as a means for securingthe pump to the timber used t0 hold it in the well.

It will be seen from the above description that the pump and alsowater-receiving vessel G are secured together in such a manner that ahollow piston-rod can be practically used as a means for discharging thewater from the body of the pump into said vessel, from which the watercan be conducted by a stationary discharge-pipe leading to the airchamber, and thence out at the top of the well. The advantage of thisarrangement over the detached receiving-vessel is, that the pump can beset up and putin working order with much greater facility than hitherto,and also that the settling or warping ofthe timber which sustains thepump will not in any manner change the position of the working parts orcause thev pistonvrod to bind or work hard in its packingboxes.

The entire pump is rendered simple and compact by my invention, and lessexpense attends its construction.

Having th us described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. Casting or otherwise applying a receivingvessel, G, directly to thebody of the pump in such manner that the water shall be forced throughthe piston-rod into this vessel before entering the discharge-pipe,substantially as described.

V2. Passing the pistonrod up through the receiving-vessel G, when thelatter vis secured to the body of the pump, substantially as' described.

3.v In a pump having a receiving-vessel, G, applied directly to it,connecting the pumprod to a hollow piston-rod at a point directly abovesaid vessel, substantially as described.

4. Conducting the water from a receivingvessel, G, having a piston-rodpassing through it, and otherwise operating substantially as described.l

5. Introducing a water-tight packing for the piston-rod between thechamber of vessel G and the pump-cylinder through it', substantially asdescribed.

6. Constructing the receiving-vessel G and the cylinder of the pump withan annular recess within the neck ot' the former, adapted for receivingany suitable material J'or packing the piston-rod, substantially asdescribed.

7. Providing for renewing the packing in the annular recess h when thevessel G and pump cylinder are cast in one piece by means of openings t't', substantially as described.

8. Closing the piston-rod C above the openings g g, substantially as andfor the purposes described.

9. Applying the receiving-vessel G, either by casting or otherwise,directly to the body of a pump having a hollow piston-rod, substantiallyas described.
